Hello, when i edit a node in a language but with the interface in a other language, some links disappears, it's because of the selection mode.
I can correct this with the preserve language module but it had some bad behaviors with others modules.

I corrected this bug by commenting these lines (in i18n_selection_mode function of i18n.module) :

I will try this out and report back, though, it would be nice for a clown like me if you could make an actual patch file. If I was better at this I would. Who knows if I can find the time I may just try.

1) Install EN, FR , NL
2) Set content negotiation to mixed
3) Install the "usernews" module
4) Post 3 EN usernews topics
5) Translate one of the 3 to NL and FR
6) Add the latest news default block
7) It will not show the EN only nodes when switched to NL or FR
